SPECIFICATION forming part of Letters Patent No. 548,215, dated October 22, 1895.

Apbiimin met January 2911895. serai No. 535,970. (No model.;

To all whom it may concern:

Be it knownthat we,THoMAs W ons MONT- GOMERY and JOHN STANIsLAUs RA QND, citizens of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Siphon, of which the following is a specification.

This invention relates to that class of siphonswhich are adapted for removing from cisterns and'other reservoirs sediment and other impurities which gather`there, as will be understood, and which must be removed so as to be prevented from mingling with pure water. Usually these devices consist of merely a tube or other water-conductor extending downwardly to the bottom of the receptacle or reservoir and ha-ving their upper ends projected out of the upper end of the reservoir, so as to gather the sediment and remove it, as will be understood. Our invention embodies this broad idea and is distinguished from the prior devices in that the tube for withdrawing the sediment is projected over the bottom of the reservoir and extends to the upper portion of the interior of the reservoir, it being associated with a cap or shield which divides -the water at the bottom of the reservoir from that at the upper portion, and which prevents the withdrawal of any water except that which is impregnated with the sediment. The shield or cap is also provided with a vent-tube capable of and adapted to break the vacuum within the withdrawing-tube, so as to prevent the unnecessary removal of water.

All of these features will be fully described hereinafter, and finally embodied in the claims, and they are illustrated in the drawings, wherein- Figure l represents a vertical section of a tank or cistern having our improvement supplied thereto. Fig. 2 is a detail perspective of the cap or shield, the same being shown detached from the cistern.

The numeral l indicates the cistern, which may, of course, be of any form or construction, and 2 a pipe for withdrawing the impure water. This pipe 2 extends centrally in the tank and has itsupper end terminating a short distance below the upper end of the tank, while the lower extremity of the pipe 2 below the tank is extended downwardly and thence horizontally. This horizontal extent is not essential, however, since the pipe may be extended in any direction which may suit the convenience of the user. The upper end of the pipe 2 is open, so as to permit the free entrance of water, and, of course, the lower end of the pipe must be open also, so as to permit the passage of the water out of the same.

The cap or shield comprises a tubular bar rel 3, having a closed upper end, and an open lower end terminating in a f unnel-shaped or conical base portion 4. This base portion has its lower end open, and the edge thereof is notched, so that the water may pass freely under it, while the base portion is rested upon the bottom of the tank l. The largest diameter of the base portion 4, or the lower end thereof, is equal to the diameter of the tank 1, so that the said base portion will inclose the bottom of the tank,'and consequently all the sediment that may be collected thereon.

The upper portion of the barrel 3 is provided with a vent-tube 5, which extends out horizontally and thence downwardly, and which communicates with the interior of the barrel, so as to break the vacuum formed in the pipe 2 during theoperation of withdrawing the sediment.

The cap or shield is arranged so that its barrel 3 will embrace the upper portion of the tube or pipe 2, and so that the ventetube 5 will extend downwardly and be submerged in the water at the upper portion of the tank. When the parts are in operative adjustment, the water will surroundthe cap or shield and will pass up into the same and into the pipe 2.

Supposing now that it is desired to withdraw the water and other matter which may be inclosed by the base portion 4 of the cap or shield, all that will be necessary will be to open the pipe 2, which will permit the water to flow through the same, and this ow will be continued until the water in the cistern is lowered below the open end ofthe tube 5, whereupon the previously-sealed tube 5 will be opened, thereupon breaking the vacuum within the barrel 3, or, in other words, permitting air to enter the same, which will cause IOO the water in the capor shield to be lowered; below the upper' end oflthe pipe 2. 'Ihiswwill eectually prevent the water from passingt out of the tube'2. The water drawn off by this operation will carry with it a portion' of the sediment and other impurities that may have been collectedat the `bottom of the tank or reservoir, and it will be impossible to draw off any more by means of the tube 2 until the water in the tank rises to a height` above the vent-tube 5, whereupon said p'ipe will be sealed again and the parts placed in such a condition as will permit the establish# ment of a vacuum in the pipes. Ifso desired,i the pipe 2 may be kept open all the time, which will cause it to expel or to carry 0E the. water as soon as it will rise above the level of` the tube 5. Thus theappliance may serve as.l an overflow device as well as a purierpand by this means the stale and impure -water from the bottom of the tank is drawn oft whenever `necessary without disturbing thejy pure or 'fresh Water which hasbeen placed'in: the tank and which is located at 'the-upper:` portion thereof. All of this will be under`A stood, since `it does not diter 'from theprinciple of other siphon cistern-cleaners. E

Changes inthe form, proportion, andithe` minor details of this invention may 'beren sorted to without departing'ffroin ,theprinci ple or sacrificing .any 'of the `advantages of this invention.

`Having thus described our invention, what; we claim as new, and desire tofsecureby Letters Patent, is l l. The combination with a Water receptacle, of apipe extended upwardly from its bottomv and open `atits upper end,`the lowerend of said pipe being also open `and proj ectedfl through `thebase ofthe receptacle, and acap; or shield embracing .such pipe, said `.cap `or;` shield comprising a barrel having 1a closed'` upper end and'em'bracingthe open upper end,` of the pipeiaforesaid in such manner as'to` leave an intervening space or water-way for-j adapting the water to 4pass Lfrom the interior?` of said capinto said pipe, said cap or shield` also comprising a hollowvconical base'resting upon andheldin place by the bottom oftheg water receptacle, and a downwardly extend-g ing vent opening in the upper end ofsaid bar-1 rel and inproximal relation to the open upper end of the pipe therein, substantially as and forfthe purpose specified.

r2. The combination with a water receptacle, cylindrical in shape, of apipe arising therein andllocated centrally thereof, the upper end of said pipe being open and the lower end thereof beingprojected through the base of said receptacle and also left open, and a cap or shield embracing said pipe and arranged within the water receptacle and comprising a tubular barrel closed at its upper end and embracing the open upper end of the pipe aforesaid in such manner as to leave an intervening `spaceorwaterway `for permitting thewater to pass .from the interior thereof into said pipe, a downwardly extending vent opening communicating withsaid barrel and located adjacent "to the upper end of said pipe `and a .conical base formed integrally with said barrel and `.of a diameter `correspon'dingitotheinternal diameterof said receptacle, `said conical base being `provided withbp'enings for admitting the Watertheretoandbeing supported and `held stationary upon the bottom of said receptacle, substantially as'andffor the :purpose described.

'3. The combination with awater receptacle, `of a pipe extended upwardly fromthe Abottom thereoi,','and havin'gfits upper end open and extended through :the bottoino'f 'said receptacle `and also left open, .and `a cap or shield elnbracingsaid pipe `and held stationary withinthe receptacle, said capor shield being disposed around 'the pipe aforesaid'in such .manner asileavean intervening space `which `will `permit the water :to fiiow'frornthe interior ot' 'the cap or shield into said pipe, :said cap orshieldbeing'leftaopen at its lower rend to permitthe water to enterft'he same, iand `a downwardly extendingvent in said cap ors'hield lo'catedinrproximal relation to lthe npper'open end o'fsaidgpipe, substantially as :and "forthe" purpose specified.
